The Bible tells us that Zacharius was struck dumb because of the sin of unbelief. He insulted God by not believing His promises. Perhaps you are like him. You have been struck dumb and can't speak to the unsaved, because you don't believe that God can help you reach the lost. If that's your case, do what Zacharius did. He called for a writing tablet. He found another means of communicating what he wanted to say. So, if you can't speak, don't stay dumb. Say what you want to say by writing a letter. Send an email. You can do that. Or drop tracts in places where sinners will find them. When Zacharius communicated what he had to say, the Bible tells us that he suddenly found his voice and glorified God. May that be your experience. There goes another minute. Gone forever. Go share your faith while you still have time.
